Incredible: Today's Motley Fool Epistle -- Bakken, North Dakota, USA

Link here.

"Luck is what happens when preparation meets opportunity" -- so goes the first-century Roman proverb. Twenty centuries later, it still holds good.

While shale plays like Bakken are always in the news and grab investors' attention, not all companies operating here necessarily do well. Opportunity must be backed by sound business models. Bakken player Brigham Exploration seems to be getting better at this job.

And that's just a start to a great note from MF.
